Good presentation. This example appears to illustrate a cold air-standard Otto cycle, which assumes a constant specific heat. Modeling as an air-standard Otto cycle yields a slightly different result. The thermal efficiency (cold-air standard only) also can be calculated from eta = 1 - (T1 / T2)
This feels like one of those classes where you're desperately trying to write down the notes, and then the teachers erases them XD Must admit, I did completely understand it
its amzing how hard it is to find a good example problem worked on this one was so close until totally ignores the k in the first equation. please remind me WHERE THAT COMES FROM!!!!!
Eric Jones if you have a textbook handy, check the back appendix for "Ideal gas specific heats of various common gases", and look under "air" for the k value.
Thank you so much
These 5 minutes are better than 2 hours explaining the professor
mohammed Ali bro is it constant value for k = 1.4 ( isentropic ) ?
Hakimin Ally
K=CP/CV
K=1.007/0.718=1.40
thanks bro
love how you explained it straight to the point, others love beating around the bush! thank you!
wow thank you! plz make more videos! very clear steps

I am Veryy Thankful. Awesome Explanation
Excellent video!! I literally did my homework with your video. Thanks :D

Nice one mate
Helpful video, thank you.

+Eric Jones k is specific heat constat also cp/cv givs the same result this is valid for ideal gases
Thank you to you both
bro u just saved my life, ty
Thank you so much this was so helpful and well explained!!!
Do you always choose the cv for air to be .718? Because on the tables it shows at 300k the cv is .718 but in this problem there's no 300k
Thanks Jeff
good but I want more problems like this
Thank you sir
Obrigado professor!!
Your voice reminds me of Toby from The Office
how to sreach CV
Tenks.👍🏾
Thank you
Where did 1.4 come from??? Helpp
That's the Cp/Cv for air
1.005/0.718
Isentropic exponent (k)
1.3 for triatomic and higher molecules
1.4 for diatomic (including air)
